摘　　要：以堇青石为原料,用震动热浇注成型工艺,通过调整骨料粒径等级、造孔剂及结合剂的加入量制备气孔率为48%,孔径为128μm,热稳定性好和机械强度高的高温烟气净化用多孔堇青石陶瓷支撑体材料。对影响材料性能的各种因素进行分析和探讨。Porous cordierite ceramic support materials for cleaning hot smoke-gas were prepared from cordierite by the hot-pouring and vibrating method by adjusting the grain composition and adding a pore-forming material and binder. The results have a porosity of 48%, a pore size of 128μm, excellent thermal stability, and relatively high strength, Factors affecting the properties of the materials were analysized and discussed.
